Abstract: A method for negotiations between various entities of a wireless local area network (WLAN) including negotiations between controlling nodes (CNs) and wireless access points (WAPs) and negotiations between WAPs is disclosed. These negotiations are used for the purpose of establishing the capabilities of the various entities, determining how such capabilities may be optimally divided among the negotiating entities and then dividing the capabilities among the entities based on this determination. The capabilities include those required for the operation, control and management of the WLAN entities and the encompassing WLAN. The disclosed method introduces means for flexibly accommodating the varying degrees of differences in capabilities among the WLAN entities between the WLAN entities including dynamic changes in WLAN topologies.

Abstract: A wireless communication system is provided for rapidly establishing the QoS resource on different communication networks. In this system, the NAP evaluates a network resource used by the MT, and generates the QoS history information unit indicating the evaluation result. The AAA authenticates the QoS history information unit generated by the NAP. The NAP transmits the authenticated QoS history information unit to the MT. The MT request for a resource establishment to the NAP when switching the communicating party from the NAP to the NAP, and transmits the QoS history information unit. The NAP verifies the authenticity of the QoS history information unit to the AAA when receiving the request for resource establishment from the MT and allocates the network resource to the MT based on the QoS history information unit.

Abstract: A wireless communication system is provided for configuring a multihop chain while suppressing the cost and complexity. In this system, one network controller (NC) (105) for executing the infrastructure function distributes the scheduling information to a plurality of communication entities (WCE) (110, 115, 120, 210, 215) configuring the multihop chain for alternating operation in the infrastructure function mode and the client function mode. The WCE (110, 115, 120, 210, 215) alternately operates the infrastructure function and the client function according to the distributed control and operations information.

Abstract: A wireless communication system is provided for rapidly establishing the QoS resource on different communication networks. In this system, the NAP (104) evaluates a network resource used by the MT (106), and generates the QoS history information unit indicating the evaluation result. The AAA (140) authenticates the QoS history information unit generated by the NAP (104). The NAP (104) transmits the authenticated QoS history information unit to the MT (106). The MT (106) request for a resource establishment to the NAP (304) when switching the communicating party from the NAP (104) to the NAP (304), and transmits the QoS history information unit. The NAP (304) verifies the authenticity of the QoS history information unit to the AAA (140) when receiving the request for resource establishment from the MT (106) and allocates the network resource to the MT (106) based on the QoS history information unit.

Abstract: A network controller (NC) (105) that reduces the overhead exchanges for mobility events in a communications network is disclosed. Such a communications network is constituted by a wireless multihop communications network comprising a multihop chain (MH) (130) that wirelessly connects in series wireless communications entities (WCE) (110, 115) for relaying and the network controller as a first entity. Within the wireless multihop communications network a mobile node (MN) (125) wirelessly communicates with the wireless communications entity (115) located at the end of the multihop chain (130). In a communications network, the network controller (105) manages the multihop chain (130), and upon determining that the communications path has to be changed by a mobility event (ME) (141), it establishes a wireless communication between the mobile node (125) and a wireless communications entity (120) by expanding (132) the multihop chain (130).

Abstract: Systems and methods for adjusting channel access based on contention conditions in a communications network are disclosed. The invention addresses the problem of multihop communications networks with varying contention conditions. Particularly, the invention addresses the channel access for common communications channels of a single or plurality of multihop configurations.
